  • Publication number: 20240355562
    Abstract: A DC circuit breaker 25a includes: a parallel connection part formed of a mechanical switch 40 and a semiconductor switch 44; and a switch control unit 39 which is connected in series to one side of the parallel connection part. The switch control unit 39 detects a main current value i separately from an external equipment-side breaking control device 12, and, when the main current value i is greater than or equal to a threshold ?, the switch control unit 39 initiates a breaking operation without having to wait for a tripping signal from the equipment-side breaking control device 12. In this 10 breaking operation, the mechanical switch 40 is switched from on to off after the semiconductor switch 44 has been switched from off to on.
